I am restoring a Tek 5440 and I strongly suspect the timebase is bust.I am looking for an inexpensive timebase to try on. Something from the 5000-series I live in the UK.Unfortunately all options are either too expensive or in the US (shipping cost).

I have a 5B42 timebase that came with a 5223 scope many years ago, Was working when last used but as I recently sold the scope (with the digital timebase) I cannot test it for you. if you are interested then drop me a message & we can discuss.
